Description

From the original post:
GS450 GS550 GS750 NM-C821 REV 1.0 2019-15-05 WORKING BIOS 100%

BIOS dump for the Compal NM-C821 laptop board, revision 1.0, listed for the GS750 platform. The original file name also references GS450 and GS550, so check your own board carefully before using it. The uploader marked the file as tested, but that is their claim and not verified here. A BIOS dump like this is used to reprogram the SPI flash chip with a programmer after a corrupted BIOS or a failed update. Confirm that the board number and revision match yours, and back up the original chip contents before writing anything.

The catalog also lists 3 schematics, 4 boardview files, and 5 BIOS dumps for board NM-C821.

Questions about this file

How do I flash this BIOS dump?

Write it to the SPI flash chip with a programmer such as the CH341A and a SOIC8 clip. Read and keep the original contents first, and check that the chip size matches the dump.

Will this BIOS work on my board?

Only if the board number and revision match: GS750 NM-C821. Dumps from a different board or revision can leave the board dead.

What does “clean ME” mean?

The Intel ME region in the dump has been reset, so it can be used on another board of the same model. Keep your original dump and transfer serial numbers if needed.
